The invention presents a level measuring gauging system for feeding more than one microwave signal to one and the same antenna unit. The microwave signals are distinguishable from one another by a detectable characteristic. The microwave signals are distributed via channels being functionally independent of each other. The gauging system comprises a feeding means (6), which has at least two wave guide members (6a, 6b, 6c), where each one of said wave guide members receives one of said microwave signals via a signal transmission line for forwarding the microwave signal to the wave guide member (6a, 6b, 6c) and one for each wave guide member (6a, 6b, 6c) common wave guide outlet (7) at a wave guide member interconnection. |
